The buttering materials for surfacing and repairing adamite roll were developed according to the composition characteristic and service condition. And the possibility of repairing adamite rolls was investigated by using buttering layer material matching working layer material. The results show that after the buttering material surfacing on adamite rolls, the ductile pearlite precipitates around brittle martensite with high carbon content that increases the ductility of buttering layer, and no metallurgical defects are found in the buttering layer. The buttering layer has good matching with the working layer material. Consequently, the technical difficulty of unable surfacing and repairing adamtie rolls is overcomed.
